It is minecraft but you can't mine any blocks. And all recipes are removed except the 2 recipes that are required to beat the game. (Blaze rod to blaze powder, blaze powder and an ender pearl to eye of ender)
NOTE: This datapack not only removes crafting recipes, it also removes smelting, stonecutting recipes etc. That means you can't do those things either.
(Even if you could smelt an iron ore to iron ingots, how are you going to get iron ores to begin with and how are you going to use your iron? It is not like you can craft some tools, right?)
I almost forgot, do "/function nocraftingmining:uninstall" to uninstall the datapack. If you can't break blocks after uninstalling the datapack for some reason(which normally shouldn't happen) just do "/attribute @s minecraft:player.block_break_speed base set 1"
